Propylene Glycerine or Propylene Glycol

[Spoink]

Hi

I been off the cigs 10 days now ... Never intended to give up ... but always hated the idea of smoking those tar and chemical ridden cigs as a delivery system just to get nicotine

I never thought these would actually work .. especially as i was on 30+ a day .. and never had the thought about ever quitting cos i loved the act of smoking so much ... but decided to buy one of these after reading this forum ... seeing all the stuff you guys wrote sold it to me ..... and you are all right .... it works ... and was sooo easy to switch over to vaping

My question is:

I want to buy some PG ... and use it to weaken down the unflavoured 36mg ... and add some of my own flavouring

Problem is .. and i know am prob gonna feel stupid when its answered in its simplicity ... i first read that i should buy Propylene Glycerine ... then i read i should buy Propylene Glycol ?

Are Propylene Glycerine and Propylene Glycol the same thing ?
If not, which one should i buy and whats teh difference ?

Cheers in advance

You can either get Propylene Glycol or Glycerin.  The normal liquid contains Propylene Glycol.
Glycerin is thick and quite sweet, but produces massive vapour.  You can get it from Boots.  97p for 200ml.

I find mixing normal liquid and glycerin about 50/50 works well.  It does dilute the flavour of the liquid though, so
you may want to get some of the LorAnn flavours to boost that.

This is the stuff you want.

But does anyone know what you are actually supposed to do with it? Interesting thing is the stuff with honey type flavour is allowed for the under 6 year olds, so only nicotine and flavourings will become a problem. At least the base- vapour producing fluid is good.

Btw if you overdo it you can end up with a dry mouth etc. So its not all good.

BadSeed ..... That was a very swift response .... and exactly what i was looking for .....

Thanks very much for that mate ....

Had a peek in LorAnn section ...  some interesting flavours in there

Im gonna do exactly what you suggest

glycerine is used for sore throats etc............but works far better for vaping!

i use it all the time with no ill effects. as badseed said, just mix it 50/50 (i prefer 70/30........70% juice, 30% glycerine) with regular juice and vape away!

proplylene glycol is hard to purchase, so glycerine is the best option mate

i gotcha igetcha ... thanks for clearin that up man ... forgot what it feels like to be a total noob at something 

Dare say ill have more questions as i keep vaping ... really nice ppl on here ..

Here's what it says on the back of that glycerin bottle.

Uses: For the relief of coughs and soreness of the throat.  May also be used to relieve dry skin conditions.

Doesn't mention vapourising it.  Definite oversight there.

wouldnt it be great if it also said "oh, and produces kick ass vapour"

For those who might want to get some PG as well as or instead of glycerin, Kate on the other forum had mentioned this humungously long eBay link (as the forum software doesn't seem to shorten URLs!): http://cgi.ebay.co.uk/1-L-PG-MPG-Propylene-Glycol-1-2-Propanediol-99_W0QQitemZ330297638072QQcmdZViewItemQQptZUK_BOI_Medical_Lab_Equipment_Lab_Supplies_ET?hash=item330297638072&_trksid=p3286.c0.m14&_trkparms=72%3A1688|66%3A2|65%3A12|39%3A1|240%3A1318, so I take it one can assume it's the right product.

There doesn't seem to be anything less than 1 litre though, so it would last AGES I expect. It's less thick than glycerin in case anyone finds glycerin alone too thick. I'm not too sure why both are used in the liquids we buy if both have the same effect. Or is it that PG doesn't produce the same amount of vapour as glycerin?

[Spoink]

I also came across that item on ebay ... but wasnt sure of the specifics ... assumed it probably wasnt what i was looking for or i would have seen it mentioned in the forum already

proplylene glycol is hard to purchase, so glycerine is the best option mate

So if i have the choice between Glycerine, or the glycol on that ebay link, should i go for glycol ?

If so ... 1L would prob last me a life time .... does it have a shelf life .... or will it keep for ever if stored correctly

It also has these names mentioned in description ... "Methylglycol; monopropylene glycol;  PG 12;  propandiol-1.2;
propane-1.2-diol;   propilenoglicol;  propylene glycol USP;  trimethyl glycol"
Are these all different names for the same substance ... or are they a list of ingredients in the glycol .... as it says 99% glycol, i am wondering if that means these other chemicals make up the 1% .. if so, is that a bad thing ?
It also says .... FORMULA: CH3CH (OH) CH2OH

If someone can tell me for sure that this stuff would be better to use than Glycerine, i will go ahead and order

Many thanks

PG = propylene glycol
MPG = monopropylene glycol
1,2-PROPANEDIOL
Methylglycol
propandiol-1.2
propane-1.2-diol
propilenoglicol
propylene glycol USP
trimethyl glycol
CH3CH (OH) CH2OH
PG 12 (not sure what the 12 is exactly)

Are all the same chemical

'Min 99%' content is not 'medical grade', but might be 'food grade' like the above Boots glycerol (glycerine) possibly is.

Compare this with Dow USP/EP grade (United States Pharmacopeia / European Pharmacopoeia) which has 99.8% min. spec.
[BUT they've put USP in one of the synonyms above, probably an error).

Then again USP pharma-grade glycerine is 99.5-99.7%,
and my bottle of Boot glycerine says 'each 5ml contains 100% v/v'  ,
which is unlikly to be a fully accurate statement

The PG already used in E-Cigs is unlikely to be pharma-grade either (probably food grade),
so maybe the ebay PG it's good enough, want to be the guinea pig?

Personally I'd stick with the Boot's glycerine.

Yup, I actually missed the usage but, where you dilute it and put on a teaspoon. So it basically really cheap cough medicine. The interesting bit is where it relieves dry skin. So its useful for your nicotine rash then? This is actually an really weird property for something to be mixed with an irritant.

When they add the bit about vaping is when the price goes up I bet. Its still too sticky to pour on your skin though.
wouldn't want 1litre of the stuff. Great value though.

[Spoink]

Or is it that PG doesn't produce the same amount of vapour as glycerin?

Good point ... i'm sure i have read people say that glycerin does give off more vapour ... not sure if thats a good thing .. they seem to like that aspect though

..... Are all the same chemical

Cheers for clearin that up exogenesis

PROPYLENE GLYCOL   Ph Eur   500ml   £6.11 from Boots the Chemist

That seems to work out cheaper than the stuff on ebay ... may be worth looking into Bjorn ... Tho i still havent managed to get to boots for the glycerine yet ...  been trying for 2 days

So its useful for your nicotine rash then?

What's a nicotine rash L E Jay ... is it an actual rash .. or just a terminology for something ?

I will try extra hard to get to boots tomorrow ... and hopefully i will have received my flavours and flavourless juice from TW by then ....

I do have a small bottle of Glycerine from Dr.Oetker .. but it only says glycerine on it .. doesnt mention if propylene ... so gave it a miss for bein too vague .. tho it does mention its suitable for vegetarions .. great

I've used this and it seems fine. It is a little thick (all glycerin is) so i just let it down with a little vodka as i had no distilled water.

[Kaze]

Just tried pure glycerine from Boots.. the same one as BadSeed.. but it seems not creating that much vapor.. at least it's not thick at all.. should it be like that or am I doing wrong? I've put like 3-4 drops to the cart.. still dont' want to try drip because I don't have extra money for another atomizer

[exogenesis]

Viscosity of glycerine is very temperature dependant, the meaning of the below figures
aren't relevant here, but to show the relative gloopiness 

At 0'C viscosity = 12000 (thick! / solid)
at 20'C (room temp) 1400 (gloopy, difficult to measure out)
at 30'C 600 (getting runny)
at 100'C 15 (pretty thin)

(water has viscosity of 1)

What I'm saying is if you're trying to mix glycerine in a cold room, warm it up a little (perhaps put the bottle on the radiator).

I've actually seen a bottle of glycerol 'ice' in a unheated chemical cupboard, in a cold winter, weird stuff.

i am 63 been told to stop smoking i have a ,100 year  old lung ,but i couldnt stop until i watched the scottish man in videos about e/cigs not had a real cig for 4 weeks,thanks a million ::)can anyone tell me who he is would like to thank him

[cadgaboo]

I just went to my local chemist and asked for food grade glycerine, I probably paid more for it than I would have paid at say Boots or Superdrug, but I didn't want to go into Truro just for 1 thing.
I paid £1.45 for a 200ml bottle oh I got some Menthol crystals at the same time LOL.
But oh boy have you guys tried drawing this glycerine up in a needle less syringe?  it's bloomin hard going! I only wanted 10ml of the stuff to mix jeepers it was hard.

[Spoink]

i vaguely recall teh guy youre on about timeout ... remember reading about his video somewhere on here im sure ....

can you post the link to teh vid .. i havent seen it ...

much appreciated



cadgaboo .. i read someone say they warm theirs up slightly for mixing ....

aldo read people cut it with slight amount of distilled water, or vodka .. not sure if thats also to make it less dense for working with

I don't understand a little bit...

I want vape without nicotine.
If I'll buy Lorann flavors and vegetable glicerin what I shold buy additional?
just add water to vegetable glicerin and few drops of lorann flavors?

usually people mix e-juice with VG because they need nicotine.
In my case I need just mix VG with water and add few drops of Lorann flavors? Isn't it?

Can anyone tell me in ml for my mix. For example for 30 ml bottle:
1 ml Water
 3 ml Vegetable Glycerin
and add 2 drops of Lorann flavor ?

P.S. I never use before e cigarette. And I'm not sure about what buy PG or VG, but I think VG is safer. What you can recomend me for first experience?

[capt12b]

I only use PG base, I have heard that VG has unpleasant side effects such a gas (and that's not a vaping I enjoy) along with possibly upsetting your stomach. But the main reason is that I have heard that if VG is heated to over 400 degrees, it can breakdown and become toxic. Not being a chemist I wouldn't know for sure but since I love my PG I just avoid VG.

Can you send me link to that information please?

For a 30ml bottle, you'd need 30ml of ingredients
I'm not big into flavouring - but a ratio of 1ml distilled water to 27ml and flavouring to taste (off the top of my head, 0.5 to 1ml, probably) would seem to be a better bet - don't overdo the water.
